A Singapore stopover and a week split between Singapore and Malaysia need different plans. For the stopover, I would buy enough data for maps, messages and bookings. For the longer route, I would check the country list before comparing prices. A cheap Singapore package is not much help after you cross into Johor Bahru.
Among the four providers in this guide, Nomad eSIM is my starting point for fixed data: 10GB for $14 or 20GB for $21, both for 30 days. Airalo has a useful three-day unlimited pass at $11.50, Saily adds security tools and a higher daily full-speed allowance on its unlimited plans, and Holafly lets you choose unlimited phone data by trip length. Their limits differ, so the headline price is only the beginning.
This comparison covers the four services already reviewed here, not every Singapore offer on the market. Local tourist plans can be strong value too. I explain that alternative below, alongside the reasons you might prefer to arrange a travel eSIM before departure.
Best eSIM for Singapore: quick answer
- Fixed-data value among these four: Nomad eSIM, 10GB/$14 or 20GB/$21 for 30 days, on Singtel.
- A short unlimited pass: Airalo, $11.50 for three days, with 3GB/day before speeds reduce to 1Mbps.
- More daily full-speed data: Saily, $26.99 for seven days, with 5GB/day before 1Mbps, plus built-in security tools.
- Unlimited phone data by trip length: Holafly, $27.50 for seven days, with 1GB/day hotspot sharing and fair-use conditions.
How to Install Your Singapore eSIM (Before You Land)
Install on a reliable Wi-Fi connection before departure. Check your phone is unlocked and supports eSIM, save the installation instructions, and leave the travel line configured as the provider recommends. At Changi, select it for mobile data and allow a little time for it to connect.
Keep your home number available if you need bank messages, but check your home carrier’s charges for calls and texts abroad. Turn off data roaming on that home line and disable automatic mobile-data switching if it could trigger unwanted roaming. Follow the travel provider’s instructions for its own roaming setting. My eSIM activation guide covers the setup in more detail. If the line fails to connect, the eSIM troubleshooting checklist explains general checks, though any country-specific advice should be matched to Singapore.
Singapore eSIM networks: check the package, not just the brand
The network name is useful, but it is not a speed test. Your handset, supported bands, indoor reception, congestion and the roaming package all affect the connection. Here is what the official plan information lists for the packages checked.
| Provider and package | Listed Singapore network | What to watch |
|---|---|---|
| Nomad eSIM fixed data | Singtel, 5G listed | 5G still depends on device and local availability |
| Nomad eSIM unlimited | StarHub, LTE/4G listed | 2GB/day at full speed, then 1Mbps |
| Airalo fixed and unlimited | Singtel 5G + M1 LTE | Unlimited: 3GB/day, then 1Mbps |
| Holafly Singapore | Singtel | 1GB/day hotspot; fair use applies |
| Saily Singapore | Partner not named | Do not assume a particular operator from the brand alone |
Holafly’s own Singapore page warns that reception can be weaker underground, inside buildings, in nature reserves and on outlying islands such as Pulau Ubin. I would save my hotel address and essential tickets offline even for a city trip. A backup costs little effort and avoids depending on a signal at exactly the wrong moment.
Singapore eSIM prices: 28 October 2026 · USD
These are the providers’ USD prices before reader codes. Compare both the allowance and the validity: Airalo’s $4 starter lasts three days, while Nomad eSIM’s $4 starter lasts seven. A 30-day allowance is a total pool of data; a daily unlimited plan splits its full-speed allowance across each day.
For equal 10GB/30-day packages, the checked prices are Nomad eSIM $14, Saily $15.99 and Airalo $16. Holafly sells unlimited packages by duration instead. Nomad eSIM’s $14 and $21 prices are displayed promotions, so I would recheck them before making a purchase.
Nomad eSIM: fixed data and daily unlimited
| Data | Validity | USD | Network / allowance |
|---|---|---|---|
| 1GB | 7 days | $4.00 | Singtel; fixed data |
| 3GB | 30 days | $6.50 | Singtel; fixed data |
| 5GB | 30 days | $9.00 | Singtel; fixed data |
| 10GB | 30 days | $14.00 | Singtel; fixed data |
| 20GB | 30 days | $21.00 | Singtel; fixed data |
| 50GB | 30 days | $31.00 | Singtel; fixed data |
| Unlimited | 5 days | $18.00 | StarHub; 2GB/day, then 1Mbps |
| Unlimited | 10 days | $27.00 | StarHub; 2GB/day, then 1Mbps |
The fixed packages are the strongest price comparison here once you need 3GB or more. At 50GB, $31 gives a larger shared allowance without a daily 2GB split. The unlimited alternative costs $18 for five days or $27 for ten days, but it is a different package on StarHub with a daily full-speed limit.
Saily: fixed data, security tools and 5GB/day unlimited
| Data | Validity | USD | Allowance |
|---|---|---|---|
| 1GB | 7 days | $3.99 | Fixed data |
| 3GB | 30 days | $6.99 | Fixed data |
| 5GB | 30 days | $9.99 | Fixed data |
| 10GB | 30 days | $15.99 | Fixed data |
| 20GB | 30 days | $22.99 | Fixed data |
| Unlimited | 5 days | $18.99 | 5GB/day, then 1Mbps |
| Unlimited | 7 days | $26.99 | 5GB/day, then 1Mbps |
| Unlimited | 10 days | $34.99 | 5GB/day, then 1Mbps |
| Unlimited | 15 days | $48.99 | 5GB/day, then 1Mbps |
| Unlimited | 20 days | $59.99 | 5GB/day, then 1Mbps |
| Unlimited | 25 days | $65.99 | 5GB/day, then 1Mbps |
| Unlimited | 30 days | $71.99 | 5GB/day, then 1Mbps |
The seven-day unlimited plan is $26.99, one cent below Airalo’s $27, but the useful difference is the daily full-speed allowance: 5GB with Saily versus 3GB with Airalo. Saily’s partner network is not named on the Singapore page. Its ad blocker, web protection and virtual location are included tools, not a promise of a separate NordVPN subscription.
Airalo: Singtel and M1, with several validity options
| Data | Validity | USD | Allowance |
|---|---|---|---|
| 1 GB | 3 days | $4.00 | Fixed data |
| 3 GB | 3 days | $6.50 | Fixed data |
| 3 GB | 7 days | $7.00 | Fixed data |
| 5 GB | 7 days | $9.00 | Fixed data |
| 10 GB | 7 days | $15.00 | Fixed data |
| 5 GB | 15 days | $9.50 | Fixed data |
| 10 GB | 15 days | $15.50 | Fixed data |
| 20 GB | 15 days | $22.00 | Fixed data |
| 5 GB | 30 days | $10.00 | Fixed data |
| 10 GB | 30 days | $16.00 | Fixed data |
| 20 GB | 30 days | $23.00 | Fixed data |
| 50 GB | 30 days | $48.00 | Fixed data |
| Unlimited | 3 days | $11.50 | 3GB/day, then 1Mbps |
| Unlimited | 5 days | $18.50 | 3GB/day, then 1Mbps |
| Unlimited | 7 days | $27.00 | 3GB/day, then 1Mbps |
| Unlimited | 10 days | $34.50 | 3GB/day, then 1Mbps |
| Unlimited | 15 days | $48.00 | 3GB/day, then 1Mbps |
| Unlimited | 30 days | $69.00 | 3GB/day, then 1Mbps |
The $11.50 three-day unlimited pass is convenient for a short visit when you expect frequent uploads. For lighter use, Airalo’s 3GB/three-day package is $6.50, the same price as Nomad eSIM’s 3GB package with 30-day validity. Airalo’s current Singapore product lists Singtel and M1, replacing the StarHub information in the earlier version of this guide.
Holafly: unlimited phone data with a separate hotspot limit
| Unlimited duration | USD | Hotspot allowance |
|---|---|---|
| 1 days | $3.90 | 1GB/day |
| 3 days | $11.90 | 1GB/day |
| 5 days | $20.50 | 1GB/day |
| 7 days | $27.50 | 1GB/day |
| 10 days | $37.50 | 1GB/day |
| 15 days | $51.50 | 1GB/day |
| 30 days | $76.50 | 1GB/day |
Holafly’s Singapore page lists Singtel. Seven days costs $27.50, ten days $37.50, and 30 days $76.50. Unlimited phone data does not mean unlimited laptop tethering: sharing is 1GB/day. A separate Southeast Asia product covers a wider itinerary; the Singapore package should not be assumed to include Malaysia or Thailand.
For a week of ordinary navigation, messages and bookings, I would compare a fixed allowance first. For heavier daily use, compare the actual full-speed threshold and hotspot rules instead of treating every unlimited label as the same product. The tables above keep those trade-offs visible.
Best eSIM for Singapore 2026: The 4 Providers in Detail
The prices narrow the choice. The provider sections explain what changes in practice: activation deadlines, security features, daily data limits, and whether a regional package would better fit your route. The retained videos are general installation walkthroughs, not Singapore coverage tests.
Nomad eSIM: my fixed-data starting point
I would start with Nomad eSIM for a typical Singapore visit because its fixed-data prices are lower than the comparable Saily and Airalo packages checked here. The 10GB promotion is $14 for 30 days; 20GB is $21. That makes room for maps, bookings and uploads without paying for a daily unlimited allowance you may not use.
The fixed plans list Singtel with 5G access where supported. The five- and ten-day unlimited plans instead list StarHub and provide 2GB/day before reducing to 1Mbps. If you want to tether or upload a large batch of photos on one day, the fixed pool can be a better fit.
I have used Nomad eSIM in Portugal, which is the experience behind my comments on setup. It is not a claim that I have measured Singtel speeds around Singapore.

How to install Nomad eSIM before Singapore
Use the original walkthrough below to prepare on Wi-Fi. Follow the current instructions supplied with your package, especially when validity starts. This is a setup reference, not a Singapore field test.
Official source: Nomad eSIM Singapore plans. Checked 28 October 2026.
Saily: useful tools and more daily full-speed data
Saily’s fixed data is close to Airalo on price: 10GB/30 days is $15.99. The more interesting comparison is its seven-day unlimited plan at $26.99, with 5GB/day before 1Mbps. That gives a different daily budget from Nomad eSIM’s 2GB and Airalo’s 3GB.
The standard plans include an ad blocker, web protection and a virtual-location feature. Saily describes virtual location as an added travel-privacy feature, not a full VPN replacement. I would not describe a regular Singapore package as a NordVPN subscription or assume it protects unrelated hotel Wi-Fi traffic.
Hotspot sharing is allowed and draws from your allowance. Plans have a 180-day activation window. Saily does not name a Singapore carrier on the checked destination page, so that remains an uncertainty to weigh against the extra tools.
I have not personally tested Saily. This recommendation is based on its documented package details.

Airalo: flexible passes for short stays
Airalo works well as a comparison point for a short stay because it offers several fixed-data durations and unlimited passes from three days. The $11.50 three-day pass gives 3GB/day at full speed, then 1Mbps. If your usage is light, the $6.50 fixed 3GB pass is a cheaper starting point.
The current Singapore catalogue names Singtel 5G and M1 LTE for the checked packages. They are data-only, rechargeable online, and activate on first usage in the coverage area. The product data lists a 365-day activation deadline, but check the order instructions if buying far ahead.
At 10GB/30 days, Airalo is $16 against Nomad eSIM’s current $14. I would choose between them on the exact package and how you prefer to manage top-ups, rather than assume the higher price guarantees a faster connection.
I have used Airalo in Portugal. For a multi-country itinerary, compare its separate Asia package and country list; do not treat the local Singapore package as regional coverage.

Holafly: unlimited phone data by trip length
Holafly makes sense when you prefer a day-based unlimited phone plan and accept its hotspot limit. The Singapore package costs $11.90 for three days or $27.50 for seven. Its page names Singtel and allows 1GB/day of data sharing.
Fair-use controls may temporarily reduce speed. The Singapore page does not give a fixed daily handset-data threshold, so I would not promise unthrottled service throughout the trip. If your main need is laptop work, compare the hotspot rules before choosing.
I have used Holafly in Portugal, Turkey and Thailand. That gives me experience with the service, but I have not tested it in Singapore. For Singapore plus Malaysia or Thailand, choose the separate Southeast Asia plan only after checking its destination list and current terms.
The included Always On benefit provides a limited monthly backup allowance in eligible countries while the eSIM stays installed. It is separate from the main paid Singapore package. Holafly also says its travel eSIMs are not intended for domestic use in your home country.

Singapore coverage: useful expectations and sensible backups
The providers describe broad Singapore coverage, including the main tourist areas. I would still separate a general coverage claim from a promise about a specific hotel room, tunnel or island. None of the information below is a field measurement by me.
| Part of the trip | What to prepare |
|---|---|
| Changi arrival | Install beforehand; save hotel and transport details offline |
| Marina Bay, CBD and attractions | Check the package network and supported device bands |
| MRT and indoor spaces | Allow for variable reception; keep tickets available offline |
| Nature reserves or Pulau Ubin | Save directions and contacts before leaving a reliable connection |
| Johor Bahru or onward Malaysia | Buy a package explicitly including Malaysia; country-only Singapore coverage is insufficient |
Best eSIM for Singapore 2026: Travel Tips
A little preparation is more useful than buying extra data without a plan. These are the checks I would make before a Singapore trip.
- Check recent usage. Your phone’s data history is a better starting point than a generic estimate. Maps and messages use far less than video calls or cloud backups.
- Choose the country list first. For Malaysia, Thailand or Indonesia, compare a regional package against separate local plans. See Malaysia and Asia.
- Read the daily limit. Nomad eSIM unlimited has 2GB/day, Airalo 3GB/day, and Saily 5GB/day before 1Mbps. Fixed packages work differently.
- Separate hotspot from phone data. Holafly allows 1GB/day sharing. That can matter more than the unlimited label for laptop use.
- Save essentials offline. Keep your hotel address, tickets, itinerary and provider instructions accessible without data.
- Prepare apps before departure. Sign in and complete verification while your usual number is easy to reach. Do not rely on a new data-only plan to receive conventional SMS.
- Check the final price. Confirm USD or the currency you intend to pay, the reader-code discount, and the validity before checkout.

Final verdict: what I would choose for Singapore
For a Singapore-only trip with ordinary mobile use, I would start by comparing Nomad eSIM’s 10GB/30-day plan at $14 against my actual data usage. It is lower than Saily’s $15.99 and Airalo’s $16 for that same allowance and validity. The $21/20GB promotion gives more room if you expect to upload often. This is a comparison of these four providers, not a claim that no local or specialist offer can be cheaper.
For a short stay with heavier use, Airalo’s three-day unlimited pass at $11.50 is a practical alternative. For a full week, I would look closely at Saily’s $26.99 unlimited package: its 5GB/day full-speed allowance may matter more than the one-cent difference from Airalo’s weekly price. Once the daily allowance is used, both slow to 1Mbps.
Holafly fits a different preference: unlimited phone data priced for your exact trip length, with the trade-off of 1GB/day hotspot and fair-use conditions. Its seven-day price is $27.50. I would not choose it solely for heavy laptop tethering or assume that its Singapore plan includes neighboring countries.
Finally, if you want a large local allowance and do not mind the operator’s identity checks, compare a local tourist plan as well. If Malaysia or Thailand is next, make the regional country list your first decision. The strongest purchase is the plan that fits the whole itinerary, not the card with the biggest unlimited label.
